Johannes Kepler said that IF the planetary orbits are elliptical,
THEN that would explain the measurements that Tycho Brahe
spent his whole life collecting.
Isaac Newton said that IF gravity works the way he thought it does,
THEN the planetary orbits have to be elliptical.
But neither Kepler nor Newton could ever say that the orbits are REALLY ellipses.
Both of their statements are 'only theories', just like the theory of evolution.
They have never been proven.
Johannes Kepler discovered that planets have elliptical orbits in the early 17th century. Kepler's work was based on observations made by Tycho Brahe and his own mathematical calculations. His laws of planetary motion laid the foundation for modern understanding of celestial mechanics.
Kepler showed that the orbits of the planets are elliptical, with the Sun at one of the focal points. This discovery led to his laws of planetary motion, which describe how planets move in their orbits.

Johannes Kepler discovered that planets move in elliptical orbits by analyzing detailed astronomical data compiled by Tycho Brahe. Kepler's observations and calculations led to his discovery of the Three Laws of Planetary Motion, which revolutionized our understanding of celestial mechanics.
Kepler's 1st law states that the orbits of the planets around the sun and makes an ellipse. This is taught in astronomy.
Kepler's observations supported the fact that the plants orbit in an ellipse. He wrote the Laws of Planetary Motion stating all planets orbit the sun and all planets orbits are elliptical.

Kepler realised the planets orbits are not circles; they are ellipses.

Johannes Kepler.
Johannes Kepler, using measured planetary positional data provided by Tycho Brahe, showed that the orbits of the planets were ellipses ("flattened circles"), with the Sun at one focus of the eliipse.

Johannes Kepler determined that planets move in elliptical orbits around the sun in the early 17th century. His observations and mathematical calculations led to the formulation of his three laws of planetary motion.
Tycho Brahe, the eccentric Danish recluse, kept records of his observations that later enabled Kepler to establish the elliptical orbits of the planets.
That was Tycho Brahe who lived on an island near Copenhagen and employed the great Johannes Kepler as his mathematician.
